The Vancouver Chamber of Commerce claims that the mean cost of hotels in the downtown area of the city is less than in Edmonton. A random sample of 50 hotels in Vancouver (population 1) had a mean nightly rate of $109 with a standard deviation of $15. An independent sample of 60 hotels in Edmonton (population 2) had a mean nightly rate of $114 with a standard deviation of $12. In testing the hypothesis with a 5% level of significance, what is the value of the standardized test statistic and the correct conclusion?
